Interconnecting data
05 Jan 2012
A major challenge of linked data is resolving the many different identifiers representing the same object. Interconnecting data requires mappings between the identifiers used in different data sets.
To help with this issue, the NBIC BioAssist engineering team in conjunction NBIC Interoperability task force has developed a service that provides the conversion between two types of identifiers; the PubMed Identifier (PMID) which is a unique number assigned to PubMed citations of life science journal articles and the Digital Object Identifier™ (DOI) which is used for identifying digital content.
DOI’s are used to provide current information, including where the content (or information about the content) can be found on the Internet. DOI’s are a very useful identifier as they often give a direct link back to the full text scientific article.
The conversion service is available from SOAP and REST web services, and in addition, there is a SPARQL endpoint for querying the mappings.
These services can be found here: http://www.pmid2doi.org/
